I know that it is a major undertaking to completely rewrite the theme system, But the current theme system leaves a lot to be desired if someone wants to re-use their themes across multiple websites. This feature request should be able to reduce the server overhead a little bit by not having to completely compile the theme style-sheets repeatedly. This framework has a lot that can be useful, details ( and examples ) can be found on the Bootstrap website, and the Bootstrap source code is available on github.

I'm sorry, I've never used Bootstrap and have no plans to use it. As far as I know, it's not even a 'theming' engine, it's just a collection of CSS files that aim to accelerate website prototyping. In other words, there's no reason it couldn't be used alongside Wedge.

There is no theme system in Wedge. It's a skin system. It has its own way of doing things -- which is arguably way better and more powerful than SMF's. You can achieve many things with a considerable advantage: you may change HTML and CSS elements without modifying the standard files, just adding to other files you create.
